Lennox M1-5 User guide

  • Hello! I've reviewed the provided Training Toolbox Tips document for the M1-5 and M1-8 controllers. This document details how to test system cooling and heating using dip switches and pushbuttons, with separate instructions for two-stage and three-stage units. It also includes helpful tables to understand input simulations and functions. I'm ready to answer any questions you might have about these testing procedures.
